A diffusion-based generative approach that directly outputs a CAD B-rep. We represent a B-rep as a novel structured latent geometry tree format. B-rep topology is implicitly represented by node duplication.

Represent high-level CAD design concepts as a hierarchical tree of neural codes. User controls the generation or auto-completion of CAD models by specifying the target design using a code tree.

Using disentangled codebooks to generate diverse and high-quality CAD models, enhances user control, and enables efficient exploration of the CAD design space.

An explore-and-classify framework for building architectural reconstruction. Our method explores the structure space by heuristic modifications and classifing the correctness of updated results.

Monocular video dataset with ground truth annotations of 3D object pose, shape and part motion. We leverage 3D human pose for more accurate inference of the object spatial layout and dynamics.

Treat single-cycle image translation as modules that can be used recurrently where the process is bounded by mutual information constraints between the input and output images.

We use the Hamming bound to derive the optimal criteria for learning hash codes with a deep network.
